I knew when I was ill that here was home ... it was the first time it really hit me that I didn't want to be anywhere else, and that was two years after moving here. I think I felt at home here much before that, but just hadn't realized it.
None the less, I know the all at sea feeling, and the longing for a straightforward conversation without having to get all flustered, and for simply doing the shopping without thinking about it ... and without a dictionary! It's rather like a cold, coming over you in waves from time to time, and each time it's easier, because each time you know a bit more about the place and its systems, the language, the food, the weather ...
If you ever feel really homesick, I recommend a trip down to the airport, it's only on your doorstep! Just go and hang around the departures queues and listen to the people, their discussions, their unhappiness at returning to the UK, and if you get to talk to them, their jealousy too of you who can now call Tenerife home!
When you buy your new house, you'll have a blank canvas, and can design and make it whatever type of home you want ... and then there's Basil too ...
oh, and Silicon Beach as well
Have a look
HERE and
HERE and
HERE too ... you're not alone in feeling like this
